I haven't had a scout but I've had other Stübben saddles and the quality is amazing. I found this review on the Stübben Scout saddle that might be of interest to you :)
"An excellent general purpose saddle. Designed post-WWII for the Belgian Army and used by many police agencies, it's comfortable, well built, and fits my horses quite well. And 10 D-rings allow you to carry a lot of stuff.
If it has a downside it's that the smallest seat is 18" (or at least it was last time I checked, about 18 months ago). This is because when it was designed there were no women in the mounted military or police units. So the saddle was designed without women in mind. Nowadays that would not be done, but there it is.
If the saddle fits your confirmation and your horse then I'd buy it."
